Title: Optical disk device
Inventor: NISHII KANJI
IPC: G11B7/005
Filed: 1983-09-28
Abstract: PURPOSE:To realize a conversion to a high density by utilizing a frequency which is higher than a cut-off frequency of a modulation transfer function (M.T.F) of an objective lens, so that a signal of a high frequency can be recorded and reproduced. CONSTITUTION:An M.T.F. of an objective lens repeats periodically to have positive and negative values, and also has a frequency characteristic similar to a damping oscillation. Accordingly, a band in which the M.T.F. of the objective lens becomes negative first is a high frequency band in which the objective lens has a comparatively high resolving power and the band is also wide. By a signal of a frequency corresponding to a higher frequency than a cut-off frequency of the M.T.F. of the objective lens, a laser is modulated and a signal is recorded in a disk. A recorded isgnal is reproduced by detecting a reflected light from the disk by a detector. In this way, a bit length on the disk can be shortened by recording and reproduciang the signal of a higher frequency than a cut-off frequency of the M.T.F. of the objective lens, and a conversion to a high density is realized.
